Power
I had a bedroom 10" color TV. It used 60W on and 5W off (for the remote control). Being
on considerably less than 2 hours a day, it was using more KWH when off than when on.
When it had problems (and I didn't want another converter box) I got a 22" diag flat screen.
$100, any smaller isn't really cheaper. This TV used 27W on and less that 0.1W off. Its
part of my energy reduction program: eliminate waste, not services. The most notable
feature of the new energy efficient stuff, is VERY low standby/off power. Bruce Roe

Is it OK to use solid copper wire between panels and charge controller?

As well as one professional photographer I know for his digital pics. Still, I like the new lower watt LCDs. Have both CRT and LCD here and I prefer the LCD. ... hmmm... maybe because it's widescreenLeave a comment:

Well if power consumption is not an issue today's CRT produce much higher quality video than any other technology. It is mature tech, but nothing can match the video quality of a modern CRT.Leave a comment:

I remember our first TV in late 50s with the little round CRT screen. Whata difference between that and the 34 inch LCD screen I have now, traded for a few hours work.Leave a comment:

Yes, the world of electron management has come a long way.
My dad probably worked a week in order to buy our first Magnavox color tv in 1968. Today you can buy them for a couple of hours of sweat.Leave a comment:

Tube
dynamotors, all kinds of vacuum tubes. Then we got bipolar transistors, silicon diodes,
unijunctions, silicon controlled switches, & SCRs. Then some field effect transistors and
a few "integrated circuits". The last two eventually developed & defined what is possible
in power control & communications today. Rare earth magnets helped a lot, and fiber optics.
The mechanical field of connecting things together came a long way too. Soldering irons,
some wire wrap, gold plating & bonding on ceramic, printed circuits, multilayer & flex circuits,
surface mount. Fortunately, most of the wiring got sucked into the ICs. Today I can just
design a printed circuit on my laptop,
email the file, and the finished board arrives several days later. BruceLeave a comment:

I have a couple years on all of you. There were no cars built the year I was born. Bruce RoeLeave a comment:

That's the way to go, Russ. Gotta keep moving, use it or lose it. Works the same way for the mind.... which is one reason I like this site. It keeps my mind well exercised.Leave a comment:
